fl/QOLL C. F/GGE BY Z United States Patent M 3,152,596 AIR ADMITTINGSMOKERS PRODUCT Carroll C. Figge, Batavia, Ill. Filed Feb. 12, 1962,Ser. No. 172,683 1 Claim. (Cl. 131-198) An important object of theinvention is to cause a mixture of the smoke coming from the productwith external air admitted to the space between the product and thesmoker so that the air expands and as it does, it absorbs heat from atube to the smokers mouth.

A further object of the invention is to cool the smoke from the articleby admitting air from the outside of the tube or holder inserted in thesmokers mouth so that the incoming cooler air reduces the temperature ofthe tube extending to the smokers mouth and is diffused in a mixingchamber with the smoke so that the smoke stream drawn therefrom isreduced in temperature and even the color of the smoke may be changeddue to the mixture of the air with the smoke generated by the burning ofthe tobacco.

Other objects of the invention will appear in the specification and willbe more apparent from the accompanying drawings, in which:

FIG. 1 is a partly sectional elevation of a cigarette to which a smokingtip is attached.

FIG. 2 is a similar view of the invention as applied to a cigarettehaving a separate holder with an air inlet and mixing chamber.

FIG. 3 is a part sectional elevation of a cigar and a separate holdertherefor having a mixing chamber and an air inlet thereto; and

FIG. 4 is a sectional view of a portion of a pipe showing a shell orsleeve for connecting the bowl of a pipe and a mouthpiece therefor andfor providing an air inlet and a graduated control therefor in aconnector between the bowl and mouthpiece.

In many tobacco products, it is the present day boast that they producea cooler and milder smoke meaning that the burning of the mixture is notso rapid, that the smoke is filtered, or that the mixture of tobacco isnot too harsh as to be disagreeable or raw to any smoker.

In the present invention, this is overcome and the sensation of smokingis much improved by reducing the temperature of the gas, and byproducing a mixture which is more smooth, pleasing and not asobjectionable to most smokers.

Referring now more particularly to the drawings, FIG. 1 shows acigarette with an attached overlapping tip 12 providing a chamber 14spaced from the adjacent end so that tobacco 16 therein will notordinarily come in contact with the lips or tongue of the smoker. Intothis chamber 14 is inserted a tube 18 which has an angular cutoff 20 atthe inner end, the outer end being inserted through and attached to thetip or mouthpiece, substantially at right angles to the wall of the tip12 in any suitable manner. This tube may be of thin metal, paper, foil,a short quill, or any other suitable material, the inner end and thecut-off 20 being preferably located at about the center or diameter ofthe tip, and the tube may even form a stop for limiting the insertion ofthat end of the cigarette in the tip, or the tube may be inserted justat the end of the cigarette.

The object of the specific location of the cut-off 20 of the tube at thecenter of the chamber 14 is to insure that it will function as a mixingchamber for the smoke drawn inwardly from the cigarette and for the airdrawn in wardly from the outside air surrounding the tip so that thesmoke and air are thoroughly intermingled and mixed in the chamber 14.Drawing the smoke through the tip causes the tube and its cut-off to actvery much like a 3,152,596 Patented Oct. 13, 1964- syphon, the outer orcooler air being drawn into the warmer and usually somewhat coloredsmoke so that the effect is an intermingling of the outer cooler air andthe inner heated air from the cigarette which forms a cooler and mildermixture for the smoker drawn from the tip. When the smoking is finished,this tip 12 with the tube 18 therein is commonly discarded with theremaining attached extremity of the cigarette 10, and thereforeconstitutes a throw away product.

In this construction, the outlet is located at the approximate radialcenter of the mixing chamber, and discharges toward the mouthpiececausing cold air from the outside to mingle with the smoke drawn fromthe smoking article, cooling and producing a milder mixture of gases forthe smoker. In the form of the invention as shown by FIG. 2, a cigarette22 is inserted at the end of a tip or cigarette holder 24 which commonlyhas a mouthpiece 26 spaced more or less from the inserted end of thecigarette and forming a mixing chamber 28 interposed between thecigarette and the mouthpiece.

Into this chamber, an air admission tube 30 is inserted which may alsobe located to limit the insertion of the cigarette into the mouthpiece,and also it has an angular inner end 32 which is bent to extend from thecigarette into the chamber 28 at the approximate center of the chamberand like the former air inner inlet tube 18 to admit outside air at thecenter of the cigarette through the mouthpiece, and thereby to induce aflow of air through the tube by drawing smoke through the mouthpiece.

This construction likewise causes an intermingling of the outside orcooler air with the smoke or gases from the cigarette, and theconsequent cooler and milder mixture of gases at the mouthpiece and to asmoker.

A similar construction is shown in FIG. 3 as applied to a cigar 34having an end opening 36 for the passage of smoke. A mouthpiece 38 istightly applied to the end of the cigar, and a short stem 40 is commonlyfound for engagement by the lips and teeth of a smoker. In thismouthpiece, there is a mixing chamber 42 and projecting inwardly fromone side of the mouthpiece is a short air inlet pipe 44 secured in thewall of the mouthpiece and having an inner bent end 46 which extendsfrom the end of the cigar into the center of the mixing chamber 42 andinjects cool air from the atmosphere to intermingle with the smoke drawnfrom the cigar around the end of the pipe 46 into the mixing chamber,thereby cooling and making a milder mixture of gases for the mouth of asmoker.

A pipe is shown in FIG. 4 having a bowl 48 with a recess 50 in whichtobacco to be smoked is placed with a passageway 52 leading from thebottom of the recess. It has a stem terminal 54 which preferablyregisters in size with a separate mouthpiece and stem 56 which isattached thereto in the ordinary pipe by sticking one into the other sothat a stern passageway 58 in the mouthpiece registers with thepassageway 52 in the stem. In the present invention, the two sternsections 54 and 56 may be joined by a metal sleeve 60 which makes asliding fit and tightly connects them both.

At one side of the sleeve is a tube 62 extending inwardly to the centerof the space forming a mixing chamber 64 in the sleeve. At the otherside of the sleeve 60, a pintle 66 having a pointed tip 68 is threadedthrough the side of the sleeve 60 and adapted to be inserted more orless into the end of the air tube 62 by a head 70.

With this construction, air is drawn from the pipe bowl recess 50through the passageway 58 of the mouthpiece stern and through the mixingchamber 64 where the air tube 62 extends to the center of the spaceforming the mixing chamber 64 so that the smoke from the bowl injectsthe cooler air into the mixing chamber and causes a thoroughintermingling of the gases with the cooler outside air. The amount ofoutside air may be varied by inserting the tip 68 of the pintle more orless into the open end of the air tube 62, or if desired, it may beclosed entirely which will give a pipe smoker a mixture of smoke of thegreatest heat and strength as compared with any possible variationthereof.

With all of these constructions, the operation is similar: drawing smokethrough the mouthpiece will cause it to be drawn through a mixingchamber to which a small stream of air is admitted for causing anintermingling of the smoke with the cooler aid which forms a cooler andmilder mixture of gases which pass to the mouth of a smoker. In onecase, means is shown for closing off entirely or admitting apredetermined amount of air to the mixing chamber which willcorrespondingly vary the mixture of the cool air With the hotter gasesfrom the article smoked.

While this construction for varying the amount of air is shown only inconnection with a pipe, it may also be supplied in the same or aslightly different form to each of the constructions shown. In somecases like that of a cigarette, an air inlet to the mixing chamber ispreferably adopted to suit the enjoyment of the majority of smokers andthus to form a predetermined cooler and milder mixture of gases for theparticular smoke in question.

While I have described a preferred construction in some detail, itshould be regarded as an illustration or example rather than as alimitation or restriction of the tobacco forming a mouthpiece and aninner mixing chamher to the end of the tip and free from tobacco, and ifshort hollow tube extending at about right angles through the wall ofthe tip to the central portion of the chamber between its ends andengaging the end of the tobacco body therein to form a stop limiting itsinsertion into the mouthpiece and the inner end of the tube beinglocated near the center of the inserted tobacco body, and having anangular cut-01f at its inner end to inject air from the outside into thechamber in smoking to mix it with smoke from the tobacco and to producea cooler and milder smoking mixture at the mouthpiece.
